National Geographic Magazine has published several articles related to the Qashqaii nomads of Persia. One of which named “We Dwelt in Kashgai Tents”, published in June 1952 (p. 805) and authored by Jean and Franc Shor tells the story of Ziyad Khan, “Father of the Horse” as the authors call him.
The authors caption the main image of the article (the image above) as:
Ziat Khan, “Father of the Horse,” Leads a Kashgai Cavalcade
The author then goes on to describe Ziad Khan’s love and devotion to his inherited ancestral horses as below:
As a sub khan of the tribe, Ziat Khan rules several thousand families. The authors found a mare and foal standing on a Persian carpet in the leader’s tent. “My prize stallion sired this colt,” he explained. “A good mount is part of a Kashgai’s family circle”.
